Monsters Inc 3 could feature original character Boo as an adult

Could a third Monsters Inc film actually happen? Well it seems that original director Pete Docter hasn’t ruled it out.

And if that long-rumoured threequel does actually happen he’s given the strongest indication yet that it could feature an all-grown-up version of Boo, the cute little girl who befriended Mike and Sully in the original.

Speaking to Entertainment Weekly Docter – who also co-directed 2015 hit Inside Out – hinted at a return for Boo, saying: ‘You never say never – who knows what will happen?

‘We purposely went with a prequel for Monsters University because we didn’t want to answer some of the questions about what happens to Boo, and how does she grow up, and things like that,’ he went on – but indicated he hasn’t ruled it out in the future, dependent on what the story might be.

‘It would have to be really compelling, which is hopefully the benchmark for all of our sequels, anyway’.

Previous rumours have suggested that Monsters Inc 3 could see the adult Boo revisiting the monsters she encountered as a child – which is clearly where Mike and Sully could come in.

But even if that does happen we’ll still have to wait a while to see it – since Pixar’s got a pretty busy slate of sequels in the next couple of years, including Cars 3 next year, The Incredibles 2 in 2018 and the fourth Toy Story movie in 2019.

Meanwhile, we didn’t want to make you feel terribly old or anything, but Mary Gibbs – who voiced Boo in the original 2001 movie – is now 20 years old (gasp!) and working as a yoga instructor. And here’s a recent Instagram snap of her:
